LEO EHRLIOII, OF ST. LOUIS, MISSOURI.

CASH-REGISTER.

SPECIFICATION :forming part of Letters Patent No. 659,141, dated October 2, 1900.

Application filed September 29, 1898. Serial No. 692,180. (No model.)

T0 all whom t may con/cern:

Be it known that I, LEO EHRLICH, a citizen of the United States, residingat St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Cash- Registers, of which the following is a specification.

My invention relates to the improvement of cash-registers, and has particular relation to that class of cash-registers in which the reg istering mechanism is operated by the movement of a cash-drawer through the medium of the swinging lever contacting with said drawer. As an example of the class of cashregisters to which my improvements are particularly applicable, I refer to patent to J. Il. McCormick, No. 610,492, dated September 6, 1898.

The object of my invention is to provide a casheregister of this class with an improved form of registering-wheel-operating lever", the utility and advantages of which will be set forth hereinafter. This object I accomplish in the manner illustrated in the accompanying drawings, in which- Figure 1 is a sectional view of a portion of a cash-register of the class to which my invention applies, showing the drawer in a closed position. Fig. 2 is a detail view in perspective showing a portion of the drawer and the means employed for preventing the same being closed until fully opened. Fig. 3 is a sectional view of a portion of the cash-register having my improvements thereon and showing the drawerin an open position, and Fig. 4is a rear elevation of a portion of the drawer and my improved lever.

Similar numerals refer to similar parts throughout the several views.

1 represents the supporti ng-framework of the mechanism; 2, the horizontal frame-plate from which said mechanism framework is supported; 3,the base,and 4 the drawer-,which in the usual manner is adapted to slide between the frame-plate 2 and base-plate 3. As indicated at 5, the central and rear portion of the frame-plate 2 is open or provided with a wide slotted opening.

Rotatably mounted upon a horizontal and transverse main shaft 6, as set forth in said former patent, are registeiingwheels, one of Which is shown in Fig. l at 7. As in said former patent, each of these registering-wheels is `provided with peripheral teeth 8, the space occupied by each of said teeth representing a money value or amount.

9 represent the yokes, which swing from the shaft 6 and the rear bars 10 of which serve to support and move, as in said former patent, the downwardly-extending stems 11 of pawl-carrying arms 12, which also swing from said shaft G. 13 represent the spring-actuated paWls which are ,carried by said arms 12 and which engage, respectively,with the teeth of the registering-wheels 7 14 represents au angular lever-bar the forward and upper end of which is mounted to swing ou said shaft 6, the downwardly-extending portion of the upper arm thereof normally forming a support for said yoke-harsh). In carrying out my improvement l provide the lever 14 with a downwardly-extending arm 15, which has a substantially foot-shaped termination 1G, the body or forward portion of which extends at an angle with the heel portion. This foot portion is provided throughout its length with a slotted opening, which consists, lirst, in a short horizontal slotted portion 17in the lower portion of the heel, the forward end of which communicates with an inclined slot-arm 18, which leads upward into the ankle portion of the foot, from which point it is continued forwardly through the body of thefoot,to the outer end or toe thereof;*as indicated at 19. The angularguideway thus formed by said slot-arms engages with or has passing loosely therethrough a transverse pin 20, which is mounted, between the arms of a bracket 21, secured to the rearside of a rear extension 22 of the drawer 4. The form of drawer catch and releasing device herein shown is substantially that indicated in said former patent and is briefly described as follows: Upon a horizontal transverse shaft or rod 23, mounted in the framework 1, is fulcrumed a bell-crank lever 24, the rear arm of this lever engaging with the shoulder 25 of an upwardly-extending arm 26 of a catch-bar 27, the rear end of said catchybar being fulcrumed, as indicated at 28, to a with said drawer-lug is effected through the medium of a preferably spring-actuated pin 30, which is mounted to slide in a bearingbracket 31 and the inner end of which is in contact with the forward arm of the bellcrank24.

The drawer being in a closed position, as indicated in Fig. 1 of the drawings, the drawer-pin 2O is locked, as shown in said figure, in the rear end portion of the short slotarm 17 and the lever 14 and yokes 9 are elevated to their limit. As shown and described in said former patent, means are employed for preventing the drawer being closed until the same has been fully opened in order to insure a complete operation of the registering and other mechanism. These means are shown in Fig. 2 of the drawings, and consist in the employment of a swinging pawl 33, supported from a bracket Si, which rises from the drawer, said pawl being adapted after the drawer has moved a short distance in an opening direction to engage with the teeth of a rack-bar 35, which is secured upon the frame-plate 2, and thereby prevent the closing of the drawer until said pawl has cleared the teeth of said bar. The engagement of the pawl 33 and bar 35 also operates to prevent the drawer being partially closed and thenv again returned to the open position, and in order to insure a proper engagement of the forward side of the pawl 33 with the rack-teeth on the outward movement of the drawer it is necessary on the closing movement of the drawer that said pawl be m'ade to travel ofi' of and past the inner end of the rack in order that it may swing to a position admitting` of the engagement of its -forward side with said rack-teeth when the drawer is again opened. In the class of cashregisters to which myinvention applies means (not herein shown) are employed tor releasing the desired yoke or yokes 9 and admitting of such released yokes falling with the downward swinging movement of their supportinglever, thus dropping the pawl o-r pawls 13 downward over a predetermined number of teeth on the registering-wheels, so that when the released yokes are again elevated the pawls will impart a movement to the registeringwheels the degree of which is dependent on the number of teeth over which said pawls have previously7 dropped. In order to illustrate the operation of the improved form of leverin which my invention primarily consists, we will assume that the drawer is in a closed position and that other parts ot' the mechanism are therefore in the positions indicated in Figs. 1 and 2 of the drawings. In order to open the drawer, the catch-bar 27 is disengaged from the lug 29 by inward pressure on the key-pin 30, after which the drawer may be pulled outward or opened to the 'full extent. In the first part of this drawer-opening movement it will be observed that the pin 20 will travel to the inner end of the slotarm 17 without in any manner affecting the position of the yokes 10 and that during the same period of time the pawl 33 will have traveled up onto the rack-bar 35 into position for engagement with the teeth thereof. The pin 2O having reached the inner end of the slot-arm 17, however, it is obvious that the lever-arm 15, together with those yoke-bars 10 which have previously been released, will drop until the pin 20 is in the upper end of the slot-arm 18. The outward pull on the drawer being continued, it is obvious that Said pin will travel through the longer slotarm 19, to the end thereo,in the mannerindicated in Fig. 3. It will be observed that by the operation above described no downward movement of the yoke-bars is attained or any operation of the registering parts of the machine until the pawl 33 is in position for engagement with the teeth of the rackbar 35. In this manner an operator of the machine is prevented from slightly opening the drawer and by closing the same again registering an amount smaller than the sale. In the return or closing movement of' the drawer it is obvious that the pin 20 will return toits position in the rear end of the slotarm 17 and that during its movement in the latter the pawl 33 will have cleared the racle bar 35 and moved to the position indicated in Fig. 2 of the drawings.

Although I have shown and described here in a particular construction of drawer-releasing mechanism, it is obvious that my device may be employed in conjunction with other drawer latching and releasing devices, and it will also be observed that the same may be employed in conjunction with a d rawer adapted to be opened by hand or byspring-pressure.

It will be readilyunderstood that the lever construction herein shown and described is not wholly dependent upon the particular form of register-operating mechanism herein shown and described,but that the same would be applicable to other machines where-in the swinging movement of said lever imparts the registering movement to the wheels.

I-Iaving now fully described myinvention, what I claim, and desire to secure by Letters Patent, is-

1. In a cash-register the combination of a series of registerwheels and a sliding cashdraweigof a slotted swinging lever pivoted coaXially with said wheels and adapted to control the movement ofthe same, and means attached to said drawer and entering the slot in said lever so that the swinging movement of the lever is produced by the opening and closing movement of the drawer,substantially as described.

2.v In a cash-register, the combination of registering-wheels, means for turning said wheels, swinging yokes for controlling said means, a sliding caslrdrawer carrying a pin, and a swinging lever for supporting said yokes, said lever having a foot termination provided with an angular slot through which said drawer-pin passes loosely, substantially as and for thepurpose specified.
